Abstract
Covalent attachment of one and two NP moieties to a ferrocenyl unit provides organometallic ligands 1,8-naphthyrid-2-yl-ferrocene (FcNP) and 1,1′-bis(1,8-naphthyrid-2-yl)ferrocene (FcNP2). Coordination of FcNP to transition metal ions FeII, CuII, ZnII, and CdII provides [FeCl2(κN8-FcNP)2] (1), [Cu(κN8-FcNP)2(NO3)2] (2), [Zn(κN8-FcNP)4][OTf]2 (3), and [Cd(κN8-FcNP)2(κ2N1,N8-FcNP)2][BF4]2 (4), respectively. Dirhodium(II) compound [Rh2(μ-FcNP)2(μ-O2CCH3)2(H2O)][OTf]2 (5) is isolated when acetonitrile-solvated [Rh2(μ-O2CCH)2]2+ is employed as a precursor. Diverse bonding modes of the NP unit, including monodentate, bidentate chelating, or binuclear bridging, are revealed in these FcNP clusters. Metallamacrocycles [M2(FcNP2)3][X]2 (M = Cu, X = ClO4 (6); M = Ag, X = OTf (7)), [PdCl2(FcNP2)] (8), and [ZnCl2(FcNP2)]4 (10) are obtained by the reaction of CuClO4, AgOTf, Pd(C6H5CN)2Cl2, and ZnCl2 with FcNP2 in 1:1 ratios. Treatment of CuI and FcNP2 in a 2:1 ratio provides [Cu2(FcNP2)][ClO4]2 (9). Molecular structures of compounds 1−10 have been determined by X-ray diffraction studies. Interconversion between 1:1 dimer 6 and 2:1 dimer 9 occurs by the addition of a requisite amount of CuI or FcNP2. ESI-MS experiments reveal that the predominant species is the 1:1 complex {Cu(FcNP2)}1+ in solution for both 6 and 9. Synthesis, structures, mass spectroscopy, and electrochemistry of the transition metal compounds of FcNP and FcNP2 are discussed.
